Track Geometry Unit

I recently made this track geometry unit to help me align my N scale code 55 track. I thought other people may be interested in it also as it works very well. I took an N scale truck and glued a nail through the bolster hole using CA glue. I then cut the nail shorter and drilled a hole (part way) in the circular level and made sure it fit on the nail with a snug fit.
I have had the circular level for many years, so I don't know where I got it. I have added the plastic bumpers to the trucks so I can push it with a loco. Since I have used it on my track I have had zero derailments. I place the unit on a known flat surface to calibrate the level. That is why I didn't glue it in place.http://model-railroad-hobbyist.com/s...metry-Unit.jpg

Good evening. I'm new to this forum, but have been building my n-scale layout for about a year. While I was building benchwork and sub-roadbed (I use pink foam), I used an app on my Android phone that shows you the grade %. I'm sure it isn't perfectly accurate, but good enough for my purposes. That app also has a level. I'm sure similar ones are available for iPhones.

Hi. Sorry for the delayed response -- it has been a busy week. Here is the link to google play store. The name of the App is Bubble level by Antoine Vianey. It also shows angle of inclination, which is a fancy way for saying grade. It is also free.

~~ I downloaded the "bubble level" app (TiltMeter)for my iPhone and it worked like a charm!! THANKS for the info! I placed the phone on a 1x3 block of wood and measured small sections of my incline/decline at a time. The block turned sideways help keep the phone above the lowest point in the track and the surrounding structures. This technique allowed me to measure 2 and 3 degree inclines smoothly! Kudos!
